It seems unlikely to me that SACD will ever support digital outs. . . just my gut feeling about the intent of the system re: copying, etc. I would definitely think it worthwhile to find a player that had a CD digital out, and a DVD digital out if you go that route.
I just don't have the time to follow the industry any longer, but it would seem to me that if SACD is heavily adopted (and I think it likely will be/is beginning to be) then you're future proof for some time with CD and SACD playback as good as it can be.
I'm a big believer in a quality source, and in the importance of a sturdy power supply and quality components in a source component; I would rank that high in what I would look for in a machine. I would at least look at a midline player, not a universal lightweight machine like the new Pioneer universal player that sells for about 175 dollars that I see people beginning to talk about elsewhere. Still, I'd be interested to hear the impressions of users of inexpensive SACD machines, ESPECIALLY re: cd playback and cdr playability.
